Lecture 3 Physiological Ecology
Evapo-transpiration the sum of water loss through evaporation and transpiration;
increases with temperature; increases the water potential difference between leaves
and the soil.

Animal (and plant) cells can be grown in culture
This requires nutrient-rich media and special surfaces
Primary cell cultures have a finite life span
